(01. 261-19) This invention relates to the manufacture of member J and serves to retain ring L and disc carbonated water, or soda water as it is gen- M in position. erally called, and also to the carbonation of other A discharge pipe V for carbonated water exbeverages, the object being to provide a continutends from a point near the bottom of reservoir ous supply of carbonated beverage by simple and A up through the top thereof.

A gas inlet in chamber A and that of the gas in chambers adapter T, provided with a non-return valve U, A and B gradually become equalized. At this is affixed to the other part of the T-fitting. sta e the gas and water supply cocks are fully A valve chamber Dis fitted into an opening in opened but no water or gas passes. The gas the bottom of reservoir A and is connected to above the level of the water in chamber A is the lower end of chamber B through an adapter compressed enabling the equilibrium. By then C and a conduit C. A pipe F extends upwardly opening the discharge cock W on pipe V, carfrom valve chamber E, which contains the nonbonated water is discharged from chamber A and return valve D, through reservoir A and into lowers the pressure of the gas above the Water a mixing chamber H formed in the member J in chamber A, thereby allow Water t0 flow fitted into an opening in the top of reservoir in through non-return valve P and gas to flow A. Pipe F is sealed to member J by a packing in through non-return valve U.

This intermingling of the is an annular ring L seated on a shoulder pro-.- gas and water in chamber H continues until the vided on the walls of chamber H. Ring L has a pressure of the gas at the top of the water in cavity L formed in the upper side thereof about the opening extending therethrough. Seated on the upper part of ring L is an annular disc M forming part of cone N provided with holes N at the top and holes N at the bottom between disc M and cone N, said holes being tangential to the center of the cone. Cone N is contained in an annular valve chamber 0 which houses a non-return valve P.

Chamber 0 is threaded into the upper end of chamber A is sufiicient to equalize the pressure of the water flowing into mixing chamber H. The carbonated water from mixing chamber H passes into chamber A via ducts H and the re plenished supply of carbonated water in chamber A is available to be drawn from pipe V. Upon Water being again drawn the pressure is lowered at the head of the water in chamber A and the entrance of gas and water to form fresh carbonated water in mixing chamber H proceeds as before described. The supply of carbonated water is thus continuously replenished.

I claim:

1. Apparatus for carbonatlng and delivering water or the like comprising a carbonated water reservoir and a gas chamber, an inlet for the gas to the gas chamber, a non-return valve in said gas inlet permitting the flow of gas into said gas chamber but preventing the return of gas from said gas chamber, an inlet for the water to said reservoir, a non-return valve in said water inlet permitting the flow of water into said reservoir but preventing the return of water from the reservoir, a discharge pipe with a cock for the discharge of carbonated water from said reservoir, a passage from the top of the reservoir to the top of the gas container, a non-return valve in said passage permitting flow through said passage from the reservoir to the chamber but preventing a reversed flow, a pipe extending from the gas chamber into said reservoir, a non-return valve in said last-mentioned pipe permitting the flow from the gas chamber into the reservoir but
